Quick answer: build each small meal around protein first, then vegetables or fruit with fiber, then some carbohydrates and healthy fat. You can get protein without shakes from Greek yogurt, cottage cheese, eggs, fish, chicken, turkey, tofu, tempeh, beans, lentils and edamame. Eat slowly, stop at the first sign of fullness, keep greasy and very sugary food low, and sip water through the day. Your clinician or a dietitian should set your personal targets.

Why does food matter more on a GLP-1?
GLP-1 medicines reduce appetite and slow stomach emptying, so many people eat far less. With less room, low-protein meals can lead to losing more muscle along with fat, and to feeling tired or shedding hair. A 2025 joint advisory from obesity and nutrition societies recommends nutrient-dense, protein-forward eating, plus strength training, for people on these medicines.
How should you build a meal?
- Protein first: a palm-sized portion, eaten first while appetite is there.
- Fiber: vegetables, fruit, beans or whole grains, to help with constipation.
- Carbs and fat in smaller amounts: enough for energy without the heavy feeling.
- Small plate, slow pace: stop when you're comfortably full. Overeating is a common nausea trigger.
How do you get protein without shakes?

| Plain Greek yogurt | 170 g (6 oz) | 15–17 g |

| Eggs | 2 large | 12 g |
| Chicken breast, cooked | 85 g (3 oz) | 26 g |

| Firm tofu | 100 g | 12–17 g |
| Lentils, cooked | ½ cup | 9 g |

Easy ways to add protein when you don't feel like eating:
- Greek yogurt with berries as a mini meal
- Cottage cheese with fruit or on toast
- Egg bites or a hard-boiled egg
- Tuna or chicken salad on crackers
- Edamame or roasted chickpeas as a snack
- Lentil or bean soup when solid food feels like too much
Which foods make GLP-1 side effects worse?
People often report more nausea, reflux and burping after:
- Greasy, fried or very rich food
- Large portions, or eating fast
- Very sugary drinks and desserts
- Carbonated drinks and alcohol
- Lying down soon after eating
See our GLP-1 side effects guide and sulfur burps post.
How much water should you drink?
Fluid needs vary. Sip through the day rather than drinking large amounts with meals, and drink more if you have diarrhea or vomiting. Dark urine, dizziness and headaches can be signs you need more.
Do you need to count calories?
Not necessarily. Many people do well by checking protein and fluid on a few typical days. Ask a dietitian if you're losing very fast, can't eat enough, or have diabetes.
Tracking it in Caliper
Caliper's meal logging has a calendar, a day view and targets you set, and water tracking has quick-add. You can see your meals alongside your dose log, check-ins and weight chart, so you can spot if nausea follows certain foods or if eating drops off after a dose step.
FAQ
What should I eat on a GLP-1?
